IPC: F25D23/06
Filed: 1923-11-13
Abstract: 224,716. Thomson, E. A. Nov. 13, 1923. Walls. - The linings or facings 3, Fig. 3, of heat insulation 4 for ship's refrigerating - chambers or for cold-storage rooms on land are made in the form of individually removable panels retained in position by wood studding or grounds 2, 2<1>. These wood grounds project outside the insulation to minimize the tendency to decay and to permit frequent observation of their condition. The panels may be curved towards the outer wall 1 to reduce the amount of insulation 4 behind them and to provide an increased passage for air circulation behind the refrigerating pipes 6. Flat wood or concrete panels may be used, or curved cork panels may be faced with a panel layer 5 of cement. The distance battens normally fitted to the walls may be constituted by the extensions of the wood grounds, or battens 10, Fig. 6, may be removably supported in cleats 11 attached to the wood grounds. The edges of the panels transverse to the studding may be shaped to provide a tongue and groove or a stepped joint, or may be moulded with recesses 25, Fig. 11, for the reception of a joint strap 23 bolted to the panels. In the case of brick chambers, Fig. 9, the studding 18 is secured by builtin bolts 17. Cork panels 19 are retained by panel linings 3<1>, which may be of cement applied after assembly. The panels are preferably formed or provided with holes closed by screw plugs to enable the condition of the enclosed insulating material to be examined. The loose insulating material 4 may be saw dust, charcoal, slagwool, granulated cork or asbestos, and the panels may be formed of one or several materials such as Portland cement and asbestos with or without reinforcement, such as expanded metal, bamboo, laths and reeds, and may be corrugated to provide stiffness and increase of air space behind the pipes.

Title: Centrifugal trip governor
IPC: G05D13/08
Filed: 1955-10-12
Abstract: 821,834. Centrifugal governors. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and LOCKETT, L. J. Jan. 4, 1957 [Oct. 12, 1955], No. 29050/55. Class 57. [Also in Group XXXI] In a centrifugal trip governor bob weights W1 W2 which move suddenly from the inner limit, or unoperated, position to the outer limit, or operated position at a predetermined speed are loaded by springs S and by a spring- loaded toggle mechanism exerting a progressively decreasing resistance to outward displacement from the unoperated position as far as the dead-centre position of the toggle mechanism and thereafter assisting displacement to the operated position, the loadings due to the springs S and the toggle mechanism being such that the resultant loading on the bob weights W1, W2 always acts to urge them inwardly towards the unoperated position and decreases with increasing displacement of the weights from the unoperated position. The bob weights W1, W2 are formed by arcuate plates pivoted at one end by pins P1, P2 to a beam M rotatably connected with a vertical drive shaft D. The other end of each bob weight is pivotally connected by a pin p1, p2 to a bobin B which rests on the beam and has on its lower face a slot L-shaped to allow relative rotation between the bobbin and beam through an angle of 30 degrees. Adjacent ends of the bob weights are interconnected by spring-loaded toggles comprising blocks T1, T2 and springs s, the pins P1, P2 and p1, p2 fitting in bores in the blocks T1 and T2 respectively. The toggle springs s oppose outward movement of the weights until they reach dead centre after which they assist centrifugal force in moving the weights outward to the operated position. The main springs S are tensioned between the bobbin and opposite ends of the beam M. A bridge-piece O rotatively fixed to the beam M by having holes in each end passing over the pins P1, P2 has on its lower face a cam C with two diametrically opposed slots. The cam enters a recess in the bobbin and is normally supported therein on two rollers R. In operation, at a predetermined speed of the shaft D, which speed may be adjusted by screws Al and A2, the bob weights move outwardly from the unoperated to the operated position thereby rotating the bobbin relative to the beam and moving the cam C over the rollers R until the latter engage the slots in the cam and the bridge O moves downwards to control a suitable safety device, for instance, to open a valve and apply a brake. Since the resultant spring force on the bob weights always tends to return them to the unoperated position the governor may, according to the design of the rollers R and slots in the cam C, be either self-resetting or non-resetting when the speed falls. In a modification, Fig. 4 (not shown), the bobbin is replaced by a bar and the main springs have their ends attached to the bob weights whose rims are provided with friction pads which, in the operated positions of the weights, engage and rotate a normally stationary clutch element to control a suitable safety device.

Title: Air operated hydraulic pump
IPC: F15B11/072
Filed: 1973-06-20
Abstract: 1404691 Reciprocating air actuated pumps; fluid-pressure control circuit OWATONNA TOOL CO 20 June 1973 [26 Dec 1972] 29339/73 Headings F1A and F1P An air actuated pump comprises a low pressure high volume chamber defined by a sleeve 30 on a piston 20, a high pressure, low volume chamber 45 defined by a block 32 and in which slides a plunger 46 on the piston 20, and air passages 22, 40 whereby air pressure may be exerted on a face of the piston 20 or on the end-faces of the sleeve 30 respectively to move the piston 20. An annular hydraulic fluid reservoir 16 surrounds the block 32. The,pump is operated by a control system to drive a hydraulic ram 50 which system has a valve 51 which in a first position, Fig. 1, for delivery permits air from a supply line 60 to act on pilot pistons 65 and 71 via a pressure regulator 53. Air pressure urges piston 65 rightwards to permit an associated poppet valve 67 to close, and urges piston 71 to the left to close an associated poppet valve 72. Air passage 22 is connected to the air supply line via a quick action diaphragm valve 83 and so piston 20 moves upwards, air passage 40 being connected to exhaust via passages 48, 100 and 76. Hydraulic fluid-flows from the two chambers via passages 37 and 47 respectively and the fluid-flows join together in a passage 92 via a check-valve 56 and thence to the device 50 via an air actuated check-valve 58 (see below). At a certain hydraulic pressure, valve 72 opens against the force of the air acting on piston 71 and fluidflows from the high volume chamber to the reservoir 16 via a return line 110. Thereafter high pressure fluid is supplied to the device 50 from the chamber 45. The maximum pressure delivered by the pump is controlled by the air pressure regulator 53. For suction, valve 51 is moved to a second position, Fig. 3 (not shown), whereby passage 76 is connected to the supply line 60 and the pressure regulator to an exhaust line 78. Consequently air moves piston 65 to the left to open valve 67 and a piston 130 of the check valve 58 to the left whereby a ball 120 is unseated to permit fluid-flow from passage 90 to passage 92 via a passage 122 in a valve part 116. As fluid pressure on the part 116 decreases the piston 130 exerts sufficient force to unseat it allowing free flow of hydraulic fluid from the device 50. Air pressure is exerted in passage 40 to retract the piston 20 and fluid-flows from the device 50 to the two pumping chambers and to the high volume chamber from the reservoir 16 via a ball-valve 230.

Title: Manufacture of colloid reliefs
IPC: G03C5/315
Filed: 1930-10-01
Abstract: 366,552. Colloid reliefs. I. G. FARBENINDUSTRIE AKT. - GES., Frankfort-on- Main, Germany. Oct. 1, 1930, No. 29399. Convention date, Dec. 6, 1929. [Class 98 (ii).] Colloid reliefs are produced by locally incorporating (e.g. by printing) or locally forming (e.g. by photography), in a colloid layer which swells in water, a heavy metal salt or a complex metal compound which reacts with alkalis or acids, and then treating the layer with an alkali or an acid of suitable concentration to dissolve those parts at which the metal compound is present leaving the pure colloid as a relief. In one photographic process a silver bromide plate after exposure behind a half-tone screen either directly or through the support, is developed with a non-hardening developer, washed (without fixing) and treated with a bleaching solution containing copper sulphate and potassium bromide. The soluble copper salts are then washed out and the layer treated with caustic soda or potash or with acetic acid to dissolve away the exposed portions of the film, leaving a positive relief image still containing the unaltered silver halide which can be developed. If caustic alkali is used it can be added to the developer, rendering separate developing unnecessary. Line originals can be reproduced by this method. Three additional photographic processes are described. In another process, local application of a zinc sulphate solution to a gelatin layer is effected manually or by printing followed by treatment with a caustic potash solution. The relief so obtained may be stained and used as a picture, or may be used indirectly for the production of a printing block, e.g. for litho printing, as by making a casting in a material of low melting point. In the Specification as open to inspection under Sect. 91 (3) (a), as an alternative to the photographic example above described, chromic acid is added to the bleaching bath and the bleached picture treated with caustic alkali without washing to obtain a negative relief. This subject-matter does not appear in the Specification as accepted.
